Overview
Classification
The process used to find out if cancer has spread within the oral cavity or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The results of the tests used to diagnose oral cavity cancer are also used to stage the disease.
- The following stages are used for lip and oral cavity cancer:
- Stage 0 (Carcinoma in Situ)
- Stage I
- Stage II
- Stage III
- Stage IV
Name | Description |
---|---|
Stage 0 | In stage 0, abnormal cells are found in the lining of the lips and oral cavity. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. |
Stage I | In stage I, cancer has formed and the tumor is 2 centimeters or smaller. Cancer has not spread to the lymph nodes. |
Stage II | In stage II, the tumor is larger than 2 centimeters but not larger than 4 centimeters, and cancer has not spread to the lymph nodes. |
Stage III | In stage III, the tumor:
may be any size and has spread to one lymph node that is 3 centimeters or smaller, on the same side of the neck as the tumor; or is larger than 4 centimeters. |
Stage IV | Stage IV is divided into stages IVA, IVB, and IVC. |
Stage IVA | In stage IVA, the tumor:
|
Stage IVB | In stage IVB, the tumor:
|
Stage IVC | In stage IVC, the tumor has spread beyond the lip or oral cavity to distant parts of the body, such as the lungs. The tumor may be any size and may have spread to the lymph nodes. |
